#8x^2+12x^2y+20xy^2+12y^2#

Since we have no variables outside the parenthesis, we can just multiply the #4# by every coefficient on the variables. We get

#8x^2+12x^2y+20xy^2+12y^2#

Hope this helps!

#8x^2 + 12x^2y + 20xy^2 + 12y^2#

#4(2x^2 + 3x^2y + 5xy^2 + 3y^2)#

Distribute (multiply) the #color(blue)4# to everything inside the parenthesis:
#8x^2 + 12x^2y + 20xy^2 + 12y^2#

Hope this helps!
